JACQUARD MECHANISM FOR LOOMS.

SPECIFICATION formingpart of Letters Patent No. 669,658, dated March 12, 1901.

Application filed November 1'7, 1900- Serial No. 36,831. (No model.)

To atZZ whom it may concern.-

Be it known that I, WALTER PATON, a subject of the Queen of Great Britain, residing at Carlisle,in the county of Cumberland, England, have invented'certain new and useful Improvements in Jacquard Mechanism for Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention refers to harness-jacquards or shedding-motions of looms, and particularly to the cross-border motion of harnessjacquards for weaving cross-borders on carpet-squares, shawls, and similar fabrics and for weaving fancy or figured goods.

The object of this invention is to provide a simple and effective cross-border motion for cross-border or fancy or figure weaving which will dispense with the complicated mechanism now employed for cross-border weaving, simplify the jacquard, and effect a considerable saving in the number of pattern-cards required.

My invention consists in the novel and peculiar arrangement and construction of parts, as hereinafter fully described, and shown on the drawings annexed.

In the drawings, Figure 1 is a diagrammatic elevation of a pair of uprights or double-lift uprights for raising the harness and ordinary horizontal jacquard-needles, showing the ap plication of my improved auxiliary set of horizontal needles comprising this invention, the two sets of needles being turned slightly around to illustrate the improvements more clearly. Fig. 2 is a plan view of the auxiliary needle, and Fig. 3 is a plan view of the ordinary jacquard-needle.

Referring to the drawings, letters a Ct represent the ordinary double-lift uprights swung upon cross-rods b b and hooked or bent into a half-circle or angle at their upper ends to project into the path of the lifter bars or knives, c 0 when unoperated by the needles, so as to be engaged by either of said lifter bars or knives which at the time is at its lowest position.

61 represents the ordinary jacquard-needle bent or looped at d d at two points of its length to receive the uprights Ct a, which register therein and are moved forward together when the needle is struck by a blank on the pattern-card presented by the cylinder 6, which operates the ordinary set of needles d.

The above parts are usual to harness-jacquards and act in the well-known manner for raising the harness, as will be well under stood by those skilled in the art to which this invention refers, one set of uprights. and one jacquard-needle only being shown, as the description with reference to one double-lift upright will apply to any number of uprights and needles of which the jacquard may be built up.

My invention comprises the application to the harness-jacquard of a second or auxiliary set of jacquard-needles f, arranged above or on a higher horizontal plane than the set of needles (1, these needles being of peculiar construction. These auxiliary needlesf (of which there are as many as the ordinary needles d to correspond with same) are placed the same way about as the bottom ordinary needles d, and this enables me to place the two respective pattern-cylinders e and g of the cross-border motion on one and the same side of the jacquard, each opposite its corresponding set of needles. The auxiliary needlesf for that portion of their length which coincides with the portion of the respective ordinary needles which extends from one side of one loop d thereon to the same side of the second loop d are bent outward to one'side to form a recess or cut-outf. Within the recess or cut-outf, at one end thereof, enters and registers one of the uprights a on one side of the auxiliary needle f, and the second upright registers in the angle adjacent to the outer opposite end of the recess, as plainly shown on the drawings.

When the ordinary jacquard-needles d are actuated, the uprights a a are free to be moved forward, as usual, the upright within the recess f in the auxiliary needlef being free to move within the limits of such recess and the upright at the outer side of the recess f moving away therefrom, whereby the auxiliary needles f are not affected or disturbed when the bottom cylinder is in action and operating according to selection on the lower and ordinary set of jacquard-needles d.

Assuming that the chain of pattern-cards on the cylinder e are for weaving the central or main body portion of a carpet-square or shawl or a figure or pattern, this said cylinder remains in action until such portion of the fabric or the pattern or figure is completed and acts solely on the needles d; but on completing the center portion, figure, or pattern and for commencing the weaving of the crossborder or ground the second cylinder g is put into action and cylinder e thrown out of action. The auxiliary needlesfare now acted upon in the order of selection by the patterncards on cylinder 9, and those that are forced forward by the blanks engage the uprights a a at f f that is, the adjacent ends of the recess or bent portion f"and move them forward to place the hooked upper ends clear of the paths of the lifter bars or knives c 0. After weaving the cross-border or the groundwork intervening between the figures or patterns being woven the cylinder g is thrown out of action and the cylinder 6 again put in action, the alternate action of the two cylinders being repeated until the whole fabric is finished.

The needles d have spiral springs 71 confined on one end thereof, as usual, to reinstate the said needles and uprights Ct at in their normal positions after each actuation. The auxiliary needles fare also provided with spiral springs j, rather lighter or weaker than the springs t', to reinstate the said needles and uprights a a after actuation. It may not, however, be necessary to apply the springsj to needles f, as the angle of the uprights a a when carried forward by the needles f will slightly move the needles d, which in being returned to their normal positions by the springst'willinsure the return of the uprights a a and needles f.

The addition of the auxiliary needles of the construction hereinbefore described in conjunction with the ordinary set of needles d and the arranging of the two cylinders e g on the same side of the jacquard enables a sin1- ple and effective cross-border motion to be obtained void of all complicated parts and, not liable to get .out of order.

The cylinders e 9 can be put into and out 5 of action by the loom or jacquard in any order of change to suit varying descriptions of fancy or figured goods, and in high-speed machines both cylinders can be brought into action alternately at half the speed of the loom.

I claim- .l. In jacquard mechanism, the combination, with uprights a, needles d, and patterncylinder c, all of approved construction; of auxiliary needles f arranged above the needles d and each provided with a single long recess f, and a second pattern-cylinder 9 arranged over the cylinder e and working alternately of it and controlling the said auxiliary needles, substantially as set forth.

2. In jacquard mechanism, the combination, with uprights a, needles d, and patterncylinder 6, all of approved construction; of auxiliary needles f arranged above the needles dand each passing between two adjacent uprights CL and provided with a single long recess f, one upright being arranged in the said recess and the other outside of the recess and on the opposite side of the needle from the first said upright, and a second pattern-cylinder 9 working alternately of the cylinder e and controlling the said auxiliary needles, substantially as set forth.

In testimony whereof I have hereunto affixed my signature in presence of two witnesses.
